sented in the following specification and the accompanying drawings,forming a part of the same.

The present invention relates to the construction of revolving doors,which are often used in a segmental casing ,to afford ingress and egressfor buildings without permitting the access of dust and drafts of air.The Wings of such revolving doors are often made of wood, and in suchcase the rails and stiles are made solid and can be 'mortised stronglytogether, which gives the wings sufficient strength to resist torsionwhen connected with the center spindle by a rigid or hinged attachment;but when it is required 'to make the wings of metal a special difiicultyarises in giving them the requisite stiffness, as it is undesirable tomake the frame of solid bars on account of the great weight which wouldbe involved. To secure lightness, metallic wing- .The object of thepresent invention is to frames have hitherto been madev of rectangularsheet-metal tubing; but it has been found exceedingly difficult toimpart sufficient "strength to the joints of the rails and stiles toresist'the lateral strain which results fromv pushing the wings aroundon the central ivot.

This object. is attained by similar means both inrespect to the two opposite wings, which are attached rigidly to thecentei spindle, and the two hinged wings, which are commonly jointed tothe s indle so that they maybe closedor swung para lel with the hingedwingswhen'it'is desired in mild weather to furnish a passage through thedoor-casing of the revolving door. V

The means referred to consists of metallic arms, which in the case ofthe rigid wings are attached rigidly to the center spindle and projectin opposite directions a therefrom,

are of such rigid character as to hold the wingframes firmly and preventthem positively outer corners of, the wing are preferably strengthenedby tubular angle-pieces and the joints of the intermediate rails bytubular ties secured Within'the ends ofthe rails and within the'breadthof the stile. By these devices the wings are so attached to the centerspindle as to revolve truly within the casing and clear the floor, theceiling, and the curved surfaces of the 'casingin the desired manner.

An embodiment of the invention is shown in the annexed drawings, inwhich- Figure 1 is a plan of the center spindle and the arms for theframes of the rigid wings fixed thereto.

In Fig. 2, (3tubular stiles of the wing-frames, which are fixed rigidly to thespindle by the means described.

D designates the end rails, which are j ointed. to the stiles by tubularangle-pieces E, (shown in Fig. 4,) and F designates the intermediaterail, jointed to the stile by a tubular tie-pieceG. (Shownin Fig-:6.)Glass plates S are shown fitted in the wings above the rails F, andornamental panels T are shown below the rails F, the glass beingnecessary to permit unrestricted observation through the wings of arevolving door. To support these wings, metallic arms H are notched intothe spindle at opposite sides and clam ed together upon the spindle bybolts P, (siiow-n in Fig. 8,) which, with the notches Q, (shown in Fig.9,) hold the arms rigidly at right angles to the spindle. The armsproject from the spindle in opposite directions into the tubu beveled todiminish its wei' ht, while the upper side fits closely within t e railsto sustain -the weight of the wing. Each of such arms intersects thenearer stile, and therefore weakens the same, and to reinforce the jointand fully restore the strength of such stile .each of such arms isprovided with an integral elbow I, which extends within such stileand'is secured therein by rivets or solder and serves to holds thestiles and rails square with one another. Similar opposite arms areshown attached to the spindle and extended into the intermediate rails Fand 'are shown provided with elbows I, extending upwardly anddownwardly, so as to strengthen the stile at such point and hold thejoint square.

The angle-pieces E and tie-pieces Gg-are shown of tubular cross-sectionin Figs. 4 to 7, inclusive, which affords both strength and lightness.to the construction, and they may be secured in the joints by rivets orby sweating solder between the. contiguous surfaces.

. Ref'errin to Figs. 3, 10, and 11, the outer stiles C of t e'hingedwings are shown jointed to the rails D and F in the same manner-as therigid wings; but the arm K, which sup-- ports the tubular wing-frame, isformed integral with a metallic stile J, which is provided .withhinge-lugs .N to engage In S M upon the center spindle. Beinforcingars Lare indie, which in Fig. 2 is designates the siaeoe so as to resistlateral pressure and to sustain the torsion and prevent distortion ofthe wings when pressed sidewise by those who use the revolving door. Theinsertion of the These reinforcing angle-pieces E andtie pieces G alsoserves to stiffen the door from lateral pressure, as well as theextension of the elbows I into the stiles adjacent to the arms H, as allof these devices contribute to stiffen the wings, and thus fit them toresist flexure under the lateral pressure to which they are subjected inuse. The junction of these stiffening devices with the center spindlerequires some special constructive features, as neither the spindle northe solid stile J can be readily formed integral with the hinge-lugswhich support thehinged wings.- The hinge-lugs N forthe wings aretherefore formed upon a foot-plate1 O, which is secured to the edge ofthe stile J by rivets or by screws R, as shown in Figs. 10 and 11. Thehinge-lugs of the spindle are formed as collars M, which are preferablconnected by an integral sleeve U, which holds them separated at asuitable distance to admit the lugs N between the collars. The

sleeve and lugs are readily attached to the 'ipindle by set-screws,(indicated at W in lar rails D, the lower side of each arm being i g.11.) A pintle V is shown connecting the hinge-lu s in Fig. 10, and thehinge connection of t e wings to the spindle is thus made strong andsecure. A special construction is also required where the arms H areattached to the spindle, as the spindle is commonly made hollow toreceivethe step-bolt B and the rod Y, which actuates the usuallockingplate at the top of the spindle. Q, which receive the inner-endsof the arms H, (see Figs. 8 and 9,) thereforematerially The notchesweakenthe spindle, and to reinforce the same a tubular plug X is driventightl within the bore of the spindle to stiffen it lietween thenotches, the central hole of the plug admitting the rod Y, which isextended to the top I of the spindle to operate the locking-plate.

In Fig. 12 the link 4 is shown where itis intersected by the lifting-pin 3, and also the sliding collar, 2 withthe handle Z projected outward through the box plate 18, throu h a slotmarked 21 in Fig. 16. To sustain the step-bolt when lifted by the handleZ, a latch-piece 15 is hinged to the lower side of the handle and formedwith a shoulder 16 to en a e the bottom of the slot 21, the pivot 17 o te latch-piece being enough to make the shoulder 16 swing forby itsgravity into engagernent with the bottom of the slot when the handle israised; When it is desiredito lower the step-bolt, the latchis readilypushed inward with the finger and disengaged from the plate 18.

It will be observed that the s indle is a straight-tube, which permitsthe s eeves carrying the hinge-collars, and the collar 2, which carriesthe handle 3, to be readily fitted and adjusted at the required pointupon the spindle. The pin 3 is screwed at its outer end within thehandle, so as to be removable from the top of the link 4, and can thusbe inserted in the top of the link when the latter is the bolt withinthe spindle. link, to be operated by its movement for liftin thelocking-plate.

The means provided for jointing the butte ends of the arms H to thespindle suffice in practice to hold those arms rigid and to'prevent anyinjurious flexure of the two rigid doors. l

. The arms L are not shown fitted tightly to the tops or bottoms of therails, but are fitted tightly to their sides, so as to hold the flatsides of the rails from bending. Such arms, as well as the arms K,formed integral with the stiles J of the hinge-doors, serve as a carrierfor the wing-frames and hold all of the rails of each wing firmly in thesame plane.
